To ALL WHOM 1T MAY eoNoERN:

Y Be it known that we, .FRANK Scnunena and NICHOLAS Annsmrrnn, of Hamilton, in the county'of Butler, and State of Ohio, have invented a new and improved Self-Itake and Reel for Harvesters; and we do hereby declare that the following is a full, clear,.and`exact description thereof, whichwill enableothers skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specil-` `tication, in which#- Figure 1 is a side View of our improved device.V

Figure 2 is a top view of the same. Y

Figure 3 is a detail sectional view, taken through the line-1o: x, iig. 1.

Figure 4 is a detail sectional View, taken through' the line y y, lig. 1.

Similarletters of reference indicate like parts. i

represents the platform, and

I3 represents a part of the frame of the harvester. g

C is the shaft from which the reel and 4rakeare suspended, and by the motion of which they are' operated.

D is a head, securely attached to the end ofl the shaft C, for the reception of the arms of the reel.

E are the arms of `the reel, upon the outer ends of which are formed sockets for the reception of the bars F, and the inner ends of which pass through holes in the head D, where they are secured in place by set-screws, as shown'in iigs. I and 2, so that theymay be adjusted as required. l

G is the rake-head, to the inner end of which is attached a shaft, H, which passes up through and works in the bearings I and J.

The bearing I slides hack and forth in a curved slot formed in the frame or quadrant K,-a.nd the bearing J rides upon the shaft C. l

To the rear side of the bearing I is pivoted a double catch, L, as shown in iig. 3, the pivoting-arm of which has a projecting finger, M, rigidly attached to its upper end.

l.N is a finger attached to the shaft I-I, just above the'heariug I, as shown in fig. l.

O is au arm attached-to the shaft HV, and having a curved rack, P, attached to its outer end, the teeth of which mesh into the .teeth of the curved rack R, connected Yto the frame or quadrant K by the arms S.

'.lo the upper end of the shaft I-I is attached an arm, T, having a friction-wheel pivoted to its outer end, as shown in figs. '.l and 2. v

U is a stop-plate, adjustabiy attached tothe frame B.

Vis a curved guideplat`e, attached to the frame B. Y

IEhe frame or quadrant K is attachedv to a sleeve or collar, W, which turns loosely upon the shaft C and in the bearing X of said shaft C.

In theend of the sleeve W are formed notches, to enable the clutch Y to take hold of it, so as tu carry the collar or sleeve, and its attachments, with the shaft C, in its revolution.

The clutch Y is held forward against the sleeve W by the spring Z, coiled around the shaft C, and pressing against the said el'uteh. y

The clutch Y is'moved away from `the sleeve W by the lever A'the forked end of which rides in a groove in the said clutch.

B is an arm pivoted to the lever A', and having a slot formed in it, which works upon the pivoting-pin of the said lever A.

'.lhe end of the arm B passes through a hole in the guide-arm C in such a position as to enter a hole formed in the frame K, and lock the said frame, holding the rake stationary, While the reel continues to operate. The said hole is formed in sueh a part of the frame K that the'arm B can enter it only when the rake is in one position, that is to say, just after the rake has left the platform.

This device is needed only in light grain, .where, at a. single revolution of the reel,- enough grain will not be cut to form a shea. v

In lusing tho machine, the parts being in the position shown in figs. 1 and 2, as the shaft C revolves, the catch takes hold of the stop-plate, and holds the sliding bearing stationary, and as the quadrant or frame K advances, thc toothed racks P and R, acting upon each other, partially revolving the rake-.shaft II, bringing the nger N into contact with the linger M, thus releasing the catch L, and allowing the rake to move on with the reel. As the rake passes over the shaft C, the friction-wheel of the arm T comes in contact with thc curved guide-plate V, revolving the rake-shaft H back, so as to bring the rake-head parallel with the bars F of the' reel, releasing the finger M from the finger N, and allowing thc spring D to bring the catch into such a position that it will take hold of the stop K', and hold the frame K and rake-'head relatively stationary until the catch again catches upon the stop-plate What we claim as new, and desire to secure by Letters Patent, is*

1. The combination of the catch L, sliding bearing I, and frame or quadrant K, with each other and with the stop U, rake-shaft H, and shaft C, substantially as herein shown and described, for the purposeof preventing any motion of the said shaft but one revolution on its axis while the'rake-head is sweeping ovcr-the platform.

2. The combination of the curved racks P and R witl'reach other and with the frame K and rake-shaft H, suostantially as herein shown and described, for the purpose of partially rotating thc shaft H, and causing the rake-head to sweep over the platform.

3. The combination of the ngers N and M with each other and with the shaft H and catch L, substantially as herein shown and described, for the purpose of releasing the catch L from the stop U at the proper time.

4, The combinationof `the clutch Y, lever A', and arm B', with each other and with the shaft C, collar or sleeve W, and frame or quadrant K, substantially as herein shown and described, and for the purpose set forth.
